So I went ahead and replaced the OEM Windshield wiper system.
On an 2018 E63s Edition 1. The wiper system is heated both internally to the tank and the hose electrically.
the mod: i decided to replace the system with the magic vision system. Now there are two different flavors.
A. The real magic vision system is on the S class. It has a hub for both the ele tribal heating of the wipers and a block with valve to direct the water to fore or aft.
B. Magic vision in the E class convertible is much simpler. The motor that controls fore and aft spraying by changing directions ton of the motor. The heated wipers are plugged into a module that controls the heat.
Parts needed:
pair of E450 convertible wiper arms
E450 cowl for magic vision.
Hose from tamk to wipers
Washer spray motor with dual output.
for wiper heaters, need to source the heating module that both wipers connect to.. can not be sourced new. Has to be from a wrecked E class convertible.
Discoveries:
The ed1 E63s has option code 875 (heated Windshield washer system).
the smarts for both option code 875 and 874 ( magic system) are in the front SAM. This is where the motor reversing takes place along with force of spray.
Without coding, the spray is a bit to strong and of course the motor does not reverse so no spray on the way down.
What works:
the heater inside the hoses works fine.
the spray works on the way up.
What does not:
No spray on way down
No wiper heater
The spray is to strong. Needs to be coded for half since it is so close.
